SSL generation failed (NXDOMAIN / 404) for mail and webmail subdomains on Tommy

[alkastraverse]

Hi Admins,

I am using a free subdomain provided by HelioHost on the Tommy server. Since I do not have direct access to manage the root DNS records for this domain extension, I am unable to resolve some SSL issuance errors via Let's Encrypt in Plesk.

When I try to secure my domain, I encounter the following issues:

1. webmail.alk.helioho.st returns a 404 Not Found during the HTTP-01 challenge.

2. mail.alk.helioho.st returns an NXDOMAIN error (missing A/AAAA records).

Could you please help me check the DNS zone configuration or manually fix the aliases/routing for these mail subdomains so they can be successfully secured?

Here are my account details:

• Main Domain: alk.helioho.st

• Server: Tommy

• Plesk Username: Alkastraverse

Thank you so much for your amazing support!
